6.4L 392 HEMI Forged 2618 Drop-In Piston Set

The Modern Muscle 6.4L 392 HEMI Forged 2618 Drop-In Piston and Rod Power Package provides a robust internal solution for owners looking to maximize the output of their Gen III HEMI engines. By using 2618 forged material and rods that match factory weight, this kit eliminates the need for balancing or removing the crankshaft, significantly reducing engine build downtime and shipping costs. The package includes MAHLE forged pistons, .217-inch wall tool steel wrist pins, and rods equipped with custom-designed ARP 2000 bolts for enhanced durability. Key performance features include a top ring moved down, an accumulator groove, a Napier oil control second ring, and coated skirts and ring lands. Compression ratios range from 9.7 to 10.1 depending on the selected head gasket. Professional installation and clearance confirmation are mandatory for this product. Oversized piston options are available, but note that they require additional engine block machining for proper fitment. This kit is designed for high-horsepower builds supporting up to 1000 RWHP, with some users reporting capabilities up to 1300 RWHP with further supporting modifications.
